LOUIS CARSTENSEN BY ATTORNEY United States Patent() 2,732,874 FOLDING DATA CASE Louis Carstensen, Portland, Oreg. Application March 9, 1953, Serial No. 341,175 2 Claims. (Cl. 150-39 This invention relates in general toa folding pocket case in which cards or slips containing reference data can be carried.

More particularly, this invention relates to a folding pocket case suitable especially for usev for salesmen, through the medium of which ready reference may be made to a plurality of price lists or similar data sheets, for comparison or otherwise.

An object of the invention is to provide an improved folding data case which, when opened, will enable a plurality of data cards and the like to be seen at a glance.

A related object of the invention is to provide a folding data case which can be used in place of a pocket sized loose leaf binder but which will be more convenient than such loose leaf binder in view of the fact that a loose leaf binder does not permit more than two pages to be viewed at the same moment.

cover, the top edge of the cover preferably being folded inwardly over the top edge of the flap 12 as shown at 15 in Figs. 2 and 3. The bottom edge 16 of the cover is preferably, though not necessarily, similarly folded inwardly on itself as a reinforcement for the cover edge.

The top edge of the flap 12 is secured to the cover either by heat sealing, stitching or other suitable means. Preferably I make the flap 12 of plastic, although it may also be made of leather, fabric or any other similar or suitable sheet material.

A series of substantially identical pockets 13 are formed on the front face of the flap 12, corresponding approximately to the fold sections of the cover 10. 'These pockets 13 are made of transparent sheet material, preferably transparent plastic, and this transparent material is secured to the flap 12 on the three sides 17 of each pocket 13 either by heat sealing, stitching or other suitable means, and the flap 12 with the pocket material secured thereto is creased along the dividing lines 18 between the pockets, these dividing crease lines 18 being in registration with the fold lines 11 in the cover 10.

A further object of the invention is to provide a folding pocket case as a container for data sheets and cards, which will protect such data sheets or cards in use, while having them always immediately available and visible upon the opening up or unfolding of the pocket case.

An additional object of the invention is to provide an improved pocket data case of the character above indicated which will be simple and inexpensive to manu facture as well as practical to use, and which will be attractive, convenient and compact in form.

The manner in which these objects are attained with my improved data case will be readily understood from the following brief description in which reference is made to the accompanying drawings.

In the drawings:

Fig. 1 is a perspective view showing my data case in normal closed or folded-up position enabling the case to be carried in a coat pocket;

Fig. 2 is a perspective view showing the data case in the process of being opened up;

Fig. 3 is an elevation showing the case fully open with half of the pockets, and the cards or data sheets contained therein, visible;

Fig. 4 is a similar elevation showing the flap, on which the card-carrying pockets are mounted, swung back so as to bring the remaining pockets, and the cards or data sheets contained therein, into view;

Fig. 5 is an enlarged section taken on line 5--5 of Fig. 4; and

Fig. 6 is an enlarged section on lines 66 of Figs. 4 and 5;

The case includes an outside cover 10 which is made of leather, plastic, or any other material suitable for wallets, pocket cases and the like. The outer cover 10 is rectangular in shape and has parallel spaced crease lines 11 dividing the cover into a plurality of rectangular sections to facilitate the folding of the cover together with the contents of the case into the folded position illustrated in Fig. 1.

A rectangular flap 12 is attached at its top edge to the corresponding top edge of the cover on the inside of the The open top edges of the pockets 13 terminate a short distance below the folded-over top edge 15 of the cover so that cards or sheets of paper of the proper size to fit in the pockets 13, the faces of which cards carry the price lists or other reference data, can be readily inserted in the respective pockets, and, when so inserted, will enable the data on the cards to be read at a glance, for comparison, cross reference, or other purposes, when the case is in the open position illustrated in Fig. 3, the data on the cards or sheets of paper being indicated at 20 in Fig.3.

On the rear face of the flap 12 a corresponding series of pockets 14 are similarly formed from the transparent material. These inner pockets 14 are open at the same edge (thus at the top edge of the cover as viewed in Figs. 2, 3 and 4) as the pockets 13. The swinging of the flap 12 back on its hinge to the position illustrated in Figs. 4 and 5, exposing the rear face of the flap, thus brings the second series of pockets 14 into view. The pockets 14 accommodate similar cards or data sheets and the data on these cards or sheets, indicated at 21 in Fig. 4, can thus be seen at a glance whenever the flap 12 is swung back.

Having the openings into the second series of pockets 14 adjacent the attached hinge edge of the flap 12 prevents the cards or data sheets from these pockets inadvertently slipping out of the pockets when the case is in the position illustrated in Figs. 2 or 3, and also leaves the hinge portion of the flap 12 free and flexible.

While the flap 12 could be made the same size as the cover 10, I prefer to have the flap 12 smaller, by one rectangular section, than the cover 10. This leaves an additional outer section of the cover to be folded over on top of the remaining portion of the case when the case is entirely folded up and thus makes a complete closure for the case with the lateral edges of the flap 12 entirely protected by the cover.

An extra pocket 19 can be formed on the inside of the outer section of the cover, if desired, as shown in Figs. 2, 3 and 4, which extra pocket can be used for extra cards, data slips, etc.

Minor modifications or additions to the data case would be possible within the scope of my invention. However, I believe the data case will be found to be most serviceable when made substantially as illustrated and described.

I claim:

1. A folding data case including a substantially rectangular-shaped cover, said cover divided into rectangular sections of approximately identical size by parallel crease lines, a rectangular-shaped flap normally positioned on the inside of said cover and attached to said cover along the top edge of said cover, said flap having parallel crease P W lc Patented'Jan. 31, 1956' lines normally registering with the crease lines in said cover, said crease lines dividing said flap into a series of rectangular sections of approximately the same size as the sections in said cover, the size of said flap not exceeding the size of .said cover, and a transparent sheet material covering substantially .an .entire face of said flap and attached to said flap along the bottom and side portions .of each of said flap :sections so as to form transparent pockets, each pocket covering substantially a face of one -.of said flap sections, said transparent sheet material being unattached to said flap for a space along the top of each flap section .so as to provide entrances into the respective pockets, the top edge of .said 'sheet material at such pocket entrances being spaced slightly below the top edge of said flap, whereby when sheets containing data are inserted in said pockets respectively the comparative .data in said pockets can .be read at a glance.

.2. A folding datacase comprising a rectangular-shaped cover, said cover divided into rectangular sections of approximately identical size =by parallel crease lines extendingparallel to the side edge of said cover, a rectangulat-shaped fiap normally positioned on the inside of said cover and hingedly attached to said cover along the top edge of said cover, said flap having parallel crease lines normally registering with .the crease lines in said cover, said crease lines dividing said flap into a series of rectangular 4 sections, said flap having one less section than said cover, and transparent sheet material covering substantially both entire faces of said flap and on each flap face attached to said flap along the bottom and side portions of said flap sections so as to form transparent pockets on both faces of said flap, each pocket covering substantially a face of one of said flap sections, said transparent sheet material being unattached to said flap for a space along the top of each flap section on both faces of said flap so as to provide entrances into the respective pockets, the top edges of said sheet material at such pocket entrances on both faces of said flap being spaced slightly below the top edge of said flap whereby. when sheets .containing data are inserted in said pockets respectively the com- 15 parative data in said pockets on whichever face of said flap is viewed can be read at a glance.
